• 
  
  we know in this game that β is dominated, is strictly dominated by α.
  我们都知道此博弈中α严格优于β
• 
  
  It's something that we learned the very first time.
  这是我们第一讲学到的东西
• 
  
  Just to check: so against α,
  验证一下 对手选α时
• 
  
  choosing α gets you 0, β gets you -1.
  你选α得0 选β得-1
• 
  
  Against β choosing α Gets you 3, β gets you 1,
  对手选β时 你选α得3而选β得1
• 
  
  and in either case α is strictly better, so α strictly dominates β,
  α严格优于β
• 
  
  and of course it's the same for the column player
  这当然对于参与人2也是同样的
• 
  
  since the game's completely symmetric.
  因为这个博弈是完全对称的
• 
  
  So now, let's find the Nash Equilibrium in this game.
  下面我们来寻找这个博弈的纳什均衡
• 
  
  I think we know what it's going to be,
  我觉得我们知道纳什均衡是什么
• 
  
  but let's just do it in this sort of slow way.
  但我们还是仔细分析一下
• 
  
  So, the best response to α must be α.
  α的最佳对策是α
